Step-by-Step Guide to Build Your AR-15

Step 1: Gather Your Tools and Components

To successfully build your AR-15, you will need the right tools and parts. Here’s a list of what you’ll need:

Tools:

• Armorer’s wrench
• Torque wrench
• Punch set
• Allen wrenches
• Screwdrivers
• Safety glasses and gloves

Components:

• Lower receiver
• Upper receiver
• Barrel
• Bolt carrier group
• Handguard
• Stock
• Lower parts kit

Important Note: Always check local laws and regulations regarding firearm assembly and ownership before starting your build.

Step 2: Assemble the Lower Receiver

1. Install the Trigger Group:

   • Begin by inserting the trigger, disconnector, and hammer into the lower receiver according to the lower parts kit instructions. Use the appropriate punches and the hammer to secure them in place.

2. Attach the Safety Selector:

   • Insert the safety selector lever into the designated hole, making sure it engages with the trigger mechanism.

3. Install the Pistol Grip:

   • Attach the pistol grip to the lower receiver. Typically, this involves inserting a screw from the bottom of the grip up into the receiver.

4. Attach the Buffer Tube:

   • Screw the buffer tube into the back of the lower receiver. Make sure it is torqued properly, as it will hold the buffer assembly and stock.

Step 3: Assemble the Upper Receiver

1. Install the Barrel:

   • Place the barrel into the upper receiver and secure it with the barrel nut. Use the armorer’s wrench and torque wrench to tighten it to the manufacturer’s specifications.

2. Install the Gas Block and Tube:

   • Slide the gas block onto the barrel and insert the gas tube. Ensure everything is aligned correctly.

3. Attach the Bolt Carrier Group:

   • Insert the bolt carrier group into the upper receiver. Make sure the bolt is in the locked position and check for proper function.

4. Attach the Handguard:

   • Depending on your handguard style, it may attach directly to the barrel nut or require additional mounting hardware.

Step 4: Combine Upper and Lower Receivers

• Align the upper and lower receivers and push the takedown pins through to lock them together. Ensure they click securely into place.

Step 5: Final Checks and Function Test

Before taking your newly assembled AR-15 to the range, it’s crucial to perform a function test. Here’s how:

1. Check All Components:

   • Ensure everything is tightened to specification and that there are no loose parts.

2. Perform a Safety Function Test:

   • Cycle the action and check the safety selector. Dry fire the trigger (make sure the firearm is pointed in a safe direction).

3. Inspect the Functionality:

   • Check that the bolt carrier group moves freely and locks in place.

Tips and Techniques for Building Your AR-15

Building an AR-15 can seem daunting, but with the right approach, you can make the process smoother. Here are some tips to keep in mind:

• Take Your Time: Rushing can lead to mistakes. Allow yourself enough time to understand each step fully.
• Follow Instructions Carefully: Most parts come with assembly instructions. Don’t skip ahead without reading them.
• Use Quality Parts: Invest in reliable components; they make a difference in your firearm’s performance.
• Work in a Clean Space: A clutter-free work area minimizes distractions and makes locating parts easier.

Common Mistakes to Avoid

1. Forgetting to Read Instructions: Always read through the manual for each part to avoid misassembly.
2. Over-Tightening Components: Excessive torque can damage parts. Use a torque wrench for critical areas.
3. Ignoring Safety Precautions: Always treat your firearm as if it’s loaded, and wear protective gear.
4. Neglecting Function Tests: Don’t skip testing! It’s vital to ensure everything works as it should.

Troubleshooting Issues

• Failure to Feed: Check the magazine and ensure that the ammo is seated properly.
• Jamming: Clean the bolt carrier group and inspect for any damage or obstructions.
• Misfires: Make sure the ammo is not defective and that the firing pin is functioning properly.
